有时候 git 提交不该提交的内容或者有些 log 过于多余，在我的博客提交记录含有草稿文件，先抹去这些提交记录。本文介绍如何初始化 git commit log。

是不是很干净呢？

Ctrl + Shift + Up。当然相同内容可以使用 Command + D

参考

在使用debug需要设置$env:DEBUG = "*,-not_this"执行相应的环境。

echo $DEBUG输出相应的环境配置。Mac下是可以使用DEBUG="*" node bin/before-parse.js。

https://github.com/visionmedia/debug/blob/master/src/node.js

“dev-mac”: “ export NODE_ENV=development&& nodemon –harmony –use_strict index.js -w “,
“dev-win”: “ set NODE_ENV=development&& nodemon –harmony –use_strict index.js -w “,

windows 不太清楚，*NIX 系统下规则如下：
export NODE_ENV=production && node xxx.js 这样在当前命令行下后续的命令中读取 NODE_ENV，都会得到 production 值；
如果直接使用 NODE_ENV=production node xxx.js，则 NODE_ENV 的有效性仅限当前命令，不会对后续命令有影响。

可以使用cross-env

For someone who is using Docker toolbox (that uses docker-machine), the answers concerning boot2docker on Mac OS X is not valid. The docker-machine VM is called “default” and it exists in the /Users//.docker/machine/machines/default/ directory.

更新日志

参考

最初的起因是由于https://gist.github.com/作为submodule的时候无法更新，于是想到终端配置访问该网站。最初以为ShadowsocksX-NG配置全局代理就可以，然后并无软用。

首先你得有相关的ss账号，可以自己部署，也可以购买相关的服务。

ss服务

1

$ sublime ~/.zshrc

相关的配置信息可以从这里获取

方法1:

2

export http_proxy=http://127.0.0.1:1087
export https_proxy=http://127.0.0.1:1087

方法2:

1

export ALL_PROXY=socks5://127.0.0.1:1086

2

$ source ~/.zshrc
$ curl www.google.com

另外推荐httpie。在终端使用http命令，调试api接口

HTTPie—aitch-tee-tee-pie—is a command line HTTP client with an intuitive UI, JSON support, syntax highlighting, wget-like downloads, plugins, and more.

$ brew install httpie

使用wepy开发小程序效率提升了很多，相比使用小程序原生框架开发，开发体验提升了好几个等级。如果是从Vue过来的，可能会对wepy部分语法不熟悉，导致自己掉进想当然(Vue习惯的写法)的坑里，所以还是要熟读wepy的文档，理解一些新的概念。我个人觉得wepy是类Vue。mpvue跟Vue更加亲一些。当然还是要感谢作者@Gcaufy提供这么好的框架，这也是为何个人项目会收入到公司项目的原因吧。

是什么原因让你折腾travis？是懒!懒!懒！每次提交代码后台又要手动输一次hexo d -g，真心觉得麻烦，作为程序猿，就应该学会偷懒，可以少输几次相同的命令，心情甚是愉悦。

当然之前也有接触过travis，比如x-citravis的简单使用，团队博客的部署。

需求: 需要在自己的App直接打开京东和淘宝指定的页面。

线上的页面在华为的设备出现空白，通过真机调试发现报错如下:

Uncaught TypeError: Object function Object() { [native code] } has no method 'assign'

解决版本

Mocha默认运行test子目录里面的测试脚本。所以，一般都会把测试脚本放在test目录里面，然后执行mocha就不需要参数了。

Now try logging into the machine, with: “ssh 'root@xx.com‘“
and check to make sure that only the key(s) you wanted were added.

Redirecting to /bin/systemctl restart ssh.service
Failed to restart ssh.service: Unit not found.

centos7下重启sshd服务的操作方法
在centos7下重启服务不再是 service 服务名称 动作 这样的方式的.而是:

systemctl 动作 服务名.service

1. 查看sshd服务是否启动了.

systemctl status sshd.service

看到的这样的信息就可以确定是启动了.

1. 如果没有启动,则需要启动该服务:

systemctl start sshd.service

1. 如果需要重启sshd服务可使得

systemctl restart sshd.service

1. 设置为开机启动可使用:

systemctl enable sshd.service

项目中用vue，vue-router实现的页面在该设备下"Mozilla/5.0 (Linux; Android 5.1.1; YQ601 Build/LMY47V) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/39.0.0.0 Mobile Safari/537.36,Cosmeapp/9.1.0"空白。其他现有设备是正常的。想到可以连接真机设备进行调试，根据报错定位到相关的代码有问题，还是资源加载异常（比如cdn的资源在某些环境下异常）。然而连接usb无发审查元素。于是跑源码在本地环境下进行局域调试，结果页面也是空白。在页面注入weinre。有报错，但是不要定位，只是显示了报错。这里不得不吐槽下weinre确实不怎么好用。有看到过资料安卓的真机调试是需要客户端支持的。

开放的CDN最好是速度快，库全，支持快速检索。本文将列举国内外常用的前端静态资源CDN公共库。用开发的CDN写写demo，体验新框架的语法，但是用到生成环境，还需谨慎。虽然方便，但是万一库挂了，被人恶意注意代码，用多了影响还是很大。
